Abstract | A number of solutions use software fault tolerance techniques based on design diversity to create fault-tolerant composite services that leverage functionally equivalent services. Nevertheless, these solutions are not able to adapt themselves at runtime to cope with dynamic changes of user requirements and fluctuations in the quality of services (QoS). We propose a self-adaptive solution, called ArCMAPE, that leverages ideas from Software Product Line Engineering to support fault-tolerant composite services. In particular, we specify a feature model and product line architecture to capture the common and variable features among a number of software fault tolerance techniques based on design diversity. ArCMAPE provides software components implementing the common features, and a foundation on which plug-in components, or variable components, can be easily added to realise the target variable features. At runtime, ArCMAPE dynamically instantiates software fault tolerance techniques tailored to the specific needs of different clients and contexts by employing feature-based runtime adaptations. Outcomes obtained from an empirical study suggest the feasibility and efficiency of our solution to support self-adaptive, fault-tolerant composite services. We discuss the obtained outcomes and present directions for future work. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
